Covers c8ctl feel evaluate for validating expressions.\n---\n\n# Camunda FEEL Expressions\n\nWrite, debug, and evaluate FEEL expressions used in Camunda 8 BPMN processes, DMN decisions, and forms.\n\n## Prerequisites\n\n- c8ctl CLI installed and configured (`c8ctl add profile`) — provides `c8ctl feel evaluate`\n- Camunda 8.9+ cluster for default cluster-engine evaluation (uses `POST /v2/expression/evaluation`)\n\n## Cross-References\n\n- **camunda-bpmn**: Use when FEEL expressions are part of BPMN conditions or I/O mappings\n- **camunda-dmn**: Use when FEEL appears inside DMN — input expressions, input entries (unary tests), output entries, literal expressions\n- **camunda-forms**: Use when FEEL expressions control form validation or conditional visibility\n- **camunda-ai-agents**: Use when FEEL expressions are prompts, `fromAi()` parameter declarations, or `toolCallResult` shaping in an AI Agent process\n\n## Instructions\n\n### FEEL in Camunda\n\nFEEL is used for:\n- **Gateway conditions**: Route process flow based on variable values\n- **Input/output mappings**: Transform variables between process scopes\n- **Timer definitions**: Define durations, dates, and cycles\n- **DMN decision tables**: Define input/output rules\n- **Form validation**: Validate user input\n\nAll FEEL expressions in BPMN XML must be prefixed with `=`:\n```xml\n<bpmn:conditionExpression xsi:type=\"bpmn:tFormalExpression\">=amount &gt; 1000</bpmn:conditionExpression>\n```\n\n### Expression Evaluation\n\nTo validate and debug FEEL expressions, use `c8ctl feel evaluate`. By default this runs against the configured cluster's Scala FEEL engine — the same engine that Zeebe uses at runtime, so results match production behavior exactly.\n\n```bash\n# Simple expression\nc8ctl feel evaluate '1 + 2'\n\n# Expression with individual variables (leading = optional)\nc8ctl feel evaluate '=amount * 1.15' --var amount=100\n\n# Multiple variables\nc8ctl feel evaluate 'a + b' --var a=1 --var b=2\n\n# JSON values for complex types\nc8ctl feel evaluate 'sum(items)' --var 'items=[1,2,3]'\n\n# Bulk variables as a single JSON object\nc8ctl feel evaluate 'orderTotal > 1000 and customer.tier = \"premium\"' \\\n  --vars '{\"orderTotal\": 1500, \"customer\": {\"tier\": \"premium\"}}'\n\n# Dot-path nesting on the CLI\nc8ctl feel evaluate 'customer.name' --var customer.name=Alice\n```\n\n**Debugging workflow:**\n1. Write the expression\n2. Identify the expected variable context\n3. Evaluate via `c8ctl feel evaluate` to validate against the cluster engine\n4. If evaluation fails, fix based on error message and retry\n\n#### Offline evaluation (`--engine local`)\n\n`c8ctl feel evaluate --engine local` evaluates expressions locally using the `feelin` JavaScript engine — useful when no cluster is available. **Use only when explicitly requested or when no cluster is reachable AND the user has confirmed the fallback.** Never silently fall back.\n\n`feelin` behaves DIFFERENTLY from the Scala FEEL engine that Zeebe runs in production. Subtle differences in type coercion, function support, and date/time handling can cause an expression that passes locally to fail in the cluster (and vice versa). Always re-validate against the cluster before relying on a result obtained with `--engine local`.\n\n```bash\nc8ctl feel evaluate '=amount * 1.15' --var amount=100 --engine local\n```\n\n**Concrete divergence: `today()` returns a different type.** On the cluster engine, `today()` returns a `date` (e.g. `2026-05-12`). On `--engine local` (feelin), it returns a date-time at midnight in the local timezone (e.g. `2026-05-12T00:00:00.000+02:00`). This breaks downstream comparisons:\n\n```bash\n# cluster engine — passes\nc8ctl feel evaluate 'today() = date(\"2026-05-12\")'           # → true\n\n# local engine — fails silently\nc8ctl feel evaluate 'today() = date(\"2026-05-12\")' --engine local   # → false\n```\n\nIf a date-typed argument is required by a downstream function, the local result may also raise a type error that the cluster never sees.\n\n### Core Syntax\n\n**Data Types**: Numbers (`1`, `1.5`), Strings (`\"hello\"`), Booleans (`true`/`false`), `null`, Dates (`date(\"2024-01-15\")`), Times (`time(\"14:30:00\")`), Date-times (`date and time(\"2024-01-15T14:30:00\")`), Durations (`duration(\"P1D\")`), Lists (`[1, 2, 3]`), Contexts (`{name: \"Alice\"}`), Ranges (`[1..10]`)\n\n**Operators**: `+`, `-`, `*`, `/`, `**`, `=`, `!=`, `<`, `>`, `<=`, `>=`, `and`, `or`, `not()`, `between x and y`, `in`\n\n**If-Then-Else** (every `if` requires `else`):\n```feel\nif score >= 80 then \"A\" else if score >= 60 then \"B\" else \"C\"\n```\n\n**For Loops**:\n```feel\nfor x in [1, 2, 3] return x * 2\n```\n\n**Quantifiers**:\n```feel\nevery x in items satisfies x.price > 0\nsome x in items satisfies x.status = \"urgent\"\n```\n\n**List Operations**:\n- 1-based indexing: `list[1]`, negative: `list[-1]`\n- Filter: `items[price > 100]`\n- Projection: `items.name` extracts name from each item\n\n**Context Operations**:\n- Property access: `customer.name`\n- `get value(ctx, \"key\")`, `get entries(ctx)`\n- `context put(ctx, \"key\", value)`, `context merge(ctx1, ctx2)`\n\n### Common Patterns and Examples\n\n**Example — Gateway condition**:\n```feel\n=orderTotal > 1000 and customer.tier = \"premium\"\n```\n\n**Input mapping with transformation**:\n```feel\n=\"https://api.example.com/users/\" + string(userId)\n```\n\nThe `string()` wrapper is required, not stylistic. FEEL does not auto-coerce types in arithmetic — `\"prefix-\" + userId` (where `userId` is a number) silently evaluates to `null` with a `Can't add 'N' to '\"prefix-\"'` warning, not an error. See `references/common-patterns.md` § Type Coercion Pitfalls for the full rule and debugging tip.\n\n**Result expression (extract from API response)**:\n```feel\n={user: response.body, status: response.statusCode}\n```\n\n**Error expression (throw BPMN error on failure)**:\n```feel\n=if response.statusCode >= 400 then bpmnError(\"HTTP_ERROR\", string(response.statusCode)) else null\n```\n\n**Timer duration (FEEL required)**:\n```feel\n=\"PT\" + string(delayHours) + \"H\"\n```\n\n**Null-safe access**:\n```feel\n=if customer != null then customer.name else \"Unknown\"\n```\n\n## Troubleshooting\n\n- **FEEL_RESOLUTION_ERROR** — a variable referenced in the expression doesn't exist in the variable context at evaluation time. Run `c8ctl feel evaluate '<expr>' --vars '<json>'` with the variables you expect at runtime to confirm.\n- **Expression returns `null` unexpectedly** — typical causes: type mismatch in `+` concatenation (see `string()` rule above); 0-based indexing (use `events[1]`, not `events[0]`); calling a non-existent helper (`first()` doesn't exist); missing commas between context entries. `c8ctl feel evaluate` prints an actual null result as `<null>` in text mode to distinguish it from the FEEL string `\"null\"` (which still prints as `null`).\n\n## References\n\nFor detailed reference material, read from `references/`:\n- [function-reference.md](references/function-reference.md) — complete list of built-in FEEL functions (string, numeric, list, context, date/time, boolean)\n- [common-patterns.md](references/common-patterns.md) — date arithmetic, list filtering, multi-entry context patterns, fromAi() for agentic AI\n","tagline":"Use this skill to write, debug, evaluate, and validate FEEL (Friendly Enough Expression Language) expressions for Camunda 8 — the expression language Zeebe uses in BPMN, DMN, and Camunda Forms.\n\nUse for: gateway conditions and conditional sequence flows; service-task input/output","category":"design-creative","commerce":{"type":"unknown","billing":"unknown","amount":null,"currency":null,"sourceUrl":null,"checkedAt":null,"runtime":"unknown","purchaseUrl":null,"checkout":"external","purchaseRequiresUserConsent":true},"tags":["agent-skill"],"author":"camunda","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"recursive skill source sync","sourceDetail":"camunda/skills","creatorName":"camunda","creatorUrl":"https://github.com/camunda","sourceUrl":"https://github.com/camunda/skills/tree/main/skills/camunda-feel","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/camunda-camunda-feel#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
